    Application-specific duty profiles can have a substantial effect on the degradation of utility-scale electrochemical batteries. Here, the researchers propose a framework for controlling battery use in a manner that maximizes the life-cycle benefit of batteries, taking both tariffs and long- and short-term battery degradation into account.

    The rising share of variable renewable energy sources in the grid makes planning future power systems more complex. Zeyringer et al. present an approach that uses multiple weather-years of data and highlights the need to incorporate inter-annual weather variability into planning decisions.

    Organic tandem solar cells combining solution- and vapour-deposited layers are difficult to fabricate due to the degradation of the underlying subcell during the deposition of the next subcell. Here, Che et al. design a charge recombination layer that protects the underlying cell and leads to 15% average PCE for 2 mm2 devices and 11.5% PCE for 1 cm2 devices.

    In recent years, Middle Eastern and North African oil-exporting states have begun reforming their energy subsidies. This Perspective argues that a number of trends — both local and global — have offered political cover for the changes, and that the reforms challenge existing governance theory.

    Battery charging and discharging regimes mostly attempt to maximize potential profit by following price signals. Combining a technical understanding of batteries with financial theory, researchers now present a framework that allows optimization of economic benefits considering both potential revenues and battery degradation.

    Membrane technologies for carbon capture can offer economic and environmental advantages over conventional amine-based absorption, but can suffer from limited gas flux and selectivity to CO2. Now, a membrane based on enzymes embedded in hydrophilic pores is shown to exhibit combined flux and selectivity that challenges the state of the art.

    Quantitative scenarios from energy–economic models inform decision-making about uncertain futures. Now, research shows the different ways these scenarios are subsequently used by users not involved in their initial development. In the absence of clear guidance from modellers, users may place too much or too little confidence in scenario assumptions and results.

    Professor M Stanley Whittingham is a pioneering researcher in the development of lithium-ion batteries at Binghamton University and Kent Snyder leads battery research and development at Ford Motor Company. Nature Energy caught up with both during the Nature Conference on Materials Electrochemistry: Fundamentals and Applications held in China in January 2018.
